-10-5r+7r=10-8(-4r-5)

- 10 - 5 r + 7 r = 10 - 8 (- 4 r - 5)

r = - 2

Solution steps

- 10 - 5 r + 7 r = 10 - 8 (- 4 r - 5)

Add similar elements:

- 5 r + 7 r = 2 r

- 10 + 2 r = 10 - 8 (- 4 r - 5)

Expand

10 - 8 (- 4 r - 5) : 32 r + 50

- 10 + 2 r = 32 r + 50

Move

10

to the right side

2 r = 32 r + 60

Move

32 r

to the left side

- 30 r = 60

Divide both sides by

- 30

r = - 2

\frac{1}{3} (10 + x) = x

y = (- 2)^{2}

- 8 (1.14 + 1.6 f) = - (1.92 + 4.8 f)

m, 2 m - 6 = 4 n + 4

y = 9
